What your AI can do with Bardo
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “bardo_verify”: Verify a signature over a UTF-8 message. Public utility (no session).”
“Use “bardo_encrypt”: Sealed-box encrypt a UTF-8 plaintext to a recipient's encryption public key.”
“Use “bardo_document_status”: Check whether a signed document is revoked. `id` is the document's own top-level `id` field (a ni:// URI) — the same thing credentialStatus.”
“Use “bardo_document_revoke”: Revoke a document you issued. Proof is a fresh signature over 'revoke:' + the document's id, verified against the key its id already committ.”
How secure is the Bardo MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Bardo holds up.
Official endpoint
Operated by Bardo (bardo.id) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Bardo adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

bardo_verify — Verify a signature over a UTF-8 message. Public utility (no session).
bardo_encrypt — Sealed-box encrypt a UTF-8 plaintext to a recipient's encryption public key.
bardo_document_status — Check whether a signed document is revoked. `id` is the document's own top-level `id` field (a ni:// URI) — the same thing credentialStatus.
bardo_document_revoke — Revoke a document you issued. Proof is a fresh signature over 'revoke:' + the document's id, verified against the key its id already committ
bardo_sign — Sign a UTF-8 message with the spirit key (or a service-derived key).
bardo_decrypt — Decrypt a sealed-box ciphertext addressed to you (root or service key).

The Bardo MCP server at a glance
https://bardo.id/mcp/Questions, answered
Is there an official Bardo MCP server?
Yes — Bardo operates its own remote MCP server at bardo.id. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Bardo to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Bardo in the directory. No account or sign-in is needed. From then on, Bardo's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Bardo runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Bardo MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect Bardo in minutes. No credit card required.
